Buck declined to identify who from the campaign contacted their office.

On Tuesday, he criticized Trump for failing to denounce white supremacist groups, but when asked if he'd back the billionaire businessman if he wins the nomination, the speaker replied, "my plan is to support the nominee."

Ryan's office declined to comment on Trump saying at his Tuesday night press conference that the speaker would "pay a big price" if he doesn't get along with him.

House GOP Whip Steve Scalise brushed off Trump's comment about Ryan, telling CNN on Wednesday, "Look, I think right now that's probably his way of reaching out an olive branch to the speaker."
